'1 claims. w1. zii- 10) This invention relates to means for transferringsound record disks from a supply magazine to a phonograph turn-table andfor removing the record disks from the tum-table. More particularly, thepresent invention is concerned with the suction head of the record-disktransferring means forming a part of my application for Machines forrecording and dispensing phonograph records, Serial Number 372,532,filed December 31, 1940, andthe present application is a con-i l0tinuation-in-part of my said prior application. fIn accordance with thepresent invention and pursuant to one of the objects'thereof, thesuction head comprises means for preventing the with the central openingofthe record disk and to provide an airtight joint between the suctionhead and the record-disk along a peripheral line spaced radiallyoutwardly from the-central hole 'communication -of the interior ofsuction head 15 of the record-disk and radially outwardly beyond l thearea of .the upper disk surface to which suction is applied.

Another object of the invention is to provide a suction head providedwith means for forming a suction chamber at the top of the record diskbetween the latter and the suction head. Another object of the inventionis generally to provide a suction head of improved construcor from asupport therefor.

The above and other objects, features and advantages of the inventionwill he fully understood tion and operation for moving record-disks to 3from the following description, referencev being had to the accompanyingillustrative drawings. In the drawings:

Fig. 1 is a sectional view on the line I-I of Fig. 2, the suction headbeing shown in full lines in position over the turn-table and in dottedlines in position over the record-disk supply magazine, parts beingomitted for the sake of clearness of illustration;

tion-head in engagement with the record vdisk; Fig. 5 is. a bottom planview of the suction head.

Refening now to the drawings in detail. the

suction head I0 forming a part of theV record disk transferring means ismounted on the suction-head carrier I2 and is movable by the latter toand from .the positions illustrated in full lines and in dotted lines inFig. l1 for moving the recordldisks R, one at a time, from the supplymagazine M to the phonograph turn-table T and from' the latter to anintermediate position over A a delivery chute Q, the lower end of whichcom-- municates with a delivery opening in the front of the cabinet asillustrated in my abovementioned prior application. I

As will be presently described, the suctionhead carrier I2 is mountedfor oscillation about a vertical axis whereby to position the suctionhead above the record disks in the supply magazine and to move thetopmost record to a position on the turn-table andv thereafter to movethe record from the turn-table to a position over the discharge chute C.Also, as will be presently described, the suction head is mounted forvertical movement in relation to the suction-head` carrier I2 forengaging the topmost record in the supply magazine and for lifting saidrecord fmm the records therebelow in themagazine, for low- `ering thetransferred record to its. position on the turn-table, and for raisingthe record from theturn-table preliminary to the removal of the recordtherefrom to the discharge chute. The means for oscillating thesuction-head carrier and-for raising and lowering the suction head onthe carrier are preferably the same as clis-` closed in my priorapplication and will, therefore, not be described herein except to theextent necessary to the explanation of the operation of the suction headas deiined by .the claims in 'this application. i

The suction-head carrier I2 is a. hollow tubular member having ahorizontal part I4 and vertical parts I6 Vand I8 at the opposite endsthereof, respectively. Said suction-head carrier I2 is iixed to theupper end of a hollow vertical` shaft 20 which passes through verticalend part I6 of carrier I2. An upper end portion 22 of shaft 20 isenlarged to provide a shoulder 24 by which shaft 20 is supported invertical position on a stationary frame part 26 and for providing ashoulder 28 which is engaged by the confronting surface o'f the internalboss 30 formed in end portion I6 oi carrier I2. The upper reduced endportion 32 of shaft 20 above shoulder 28 projects yupwardly through saidboss 30 and is engaged by member I2 with an interposed lock washer 36.Shaft 28 is journalled for turning movement in a bearing bushing 38provided in frame part 26 and in a bearingbushing 48 mounted in astationary frame part 4 2. The lower end of shaft 20 is provided with agear 44 which is engaged by a companion gear member (not shown) actuatedas described in my above mentioned application for oscillating shaft 28about its vertical axis. The lower end of part I6 of carrier I2communicates with a chamber 46 in frame part 28, said chamber having anopening 48 which communicates with a source of suction as described inmy prior application.

The suction head I8 comprises a cylindrical tubular member 58 having anupper portion 52 which has a slidable and rotatable fluid-tight t withthe inner cylindrical surface 54 of the lower end portion 56 of the endpart I8 oi carrier I2. Said tubular part 58 of the suction headcommunicates with the interior of carrier member I2 through a pluralityof openings 58, the interior of member I2 being in communication withthe source of suction through chamber 46. Above said openings 8, member58 ofthe suction head is provided with an integral cylindrical portion68 which has a slidable and rotatable fluid-tight llt in an opening 62in the top of end part I8. The vertical movement of suction head I8 isprovided for by the mechanism which includes the lever 64.pivotallymounted between its ends on a pinv 66 carriedby brackets 68 at the topof carrier I2. The upper enlarged en d portion 18 of the cylindricalstem 1I of suction head is engagedby the forked end 12 of one arm oflever 64. The other arm of the lever is engaged at its end by a sleeve14 in which theend of a cable 16, such as a wire or cord, is fixed. Saidcable 16 extends longitudinally through hollow shaft 28 to a point belowthe lower end of said shaft where said cord is engaged by the mechanismdescribed in my prior application for moving said cable downwardlyandfor permitting said cable to move upwardly in timed relation to theactua-4 tion of shaft 28. It will be understood that when cable 16 ismoved downwardly, lever 64 is operated for raising the suction head andthat when said cable .is allowed to move upwardly the suction head canmove downwardly under its weight. A spring 18 secured to the top ofcarrier member I2 and bearing on lever 64 assists vthe downward movementof the suction head and resiliently opposes the upward movement thereof.Suction head I8 is provided with a flange 88 which is engageable withthe lower end portion 56 of carrier member I2 for limiting the upwardmovement of the suction head.

Suction head I8 is provided with a pick-up plate 82 which is engageablewith and disengageable from the record disk for moving the latter fromthe magazine and to the turn-table and from the turn-table to thedischarge chute. The

pick-up plate 82 comprises a disk 84 provided with a central upwardlyprojecting cylindrical portion 86 which is screw-threaded externallythereof and is threaded into the companion lower end of tubular member58 of the suction head whereby the pick-up plate 82 is removably securedto said member 58 in fluid-tight relation therewith. The lower surfaceof disk 84 is provided with a circular recess sa in which is adhesivelyor otherwise secured the circular gasket or packing ring 98. Saidpacking ring 98 is preferably resilient and may be formed of cork, softrubber or any other suitable packing material.

Pick-up plate l82 is provided with means for sealing the central openingO of the record disk from communication with the interior of the suctionhead. Said sealing means comprises a soft rubber or other resilientgasket or packing ring 92, the lower end. of which engages the uppersurface of the record disk near and completely around the centralopening O of said disk. As illustrated in Fig. 4, packing rings 98 and92 when 1 engaged with the upper surface of the record disk R. definel asuction kchamber 94 above the record-disk between the outer peripheraledge of packing 92 of the inner peripheral edge of packing 98 completelytherearound, and said packing rings prevent loss of suction which mightotherwise occur either through central opening O of the record-disk orthrough any space which might be present between the lower surface ofplate 64 and the upper surface of the record-disk,

if said plate were in direct contact with said record in the absence ofthe packing ring 90.

Gasket 92 is mounted for movement in pickup plate 82 axially thereof.For this purpose,

said packing 92 is carried by a member 96 which is provided with acentral vertical extending recess 98 for receivingthe centering pin 99oi the turn-table or the upper end'portion of the centering rod I88 ofthe supply magazine when the suction-head is positioned over theturn-table and supply magazine, respectively, in engagement wardly4thereof and connected thereto by the spider portions |86 providingopenings |88 in the pick-up plate to provide communication between theexterior of the pick-up plate and the interiorv of the suction head. Thepacking carrying mem` 9. ber 96 is provided with an upper stem I I8which projectsthrough an opening II2 in hub part |84. A pin I I4 passingthrough the outer end of stem II8 limits the downward movement of member96. A spring II6 bearing at one end thereof against member 96 and latits other end against the top of hub part |84, presses member 96 and thepacking 92 carried thereby downwardly for` resilient engagement with therecord disk. The

parts of pick-up plate 82 are so dimensioned that packing member 92 isprojected by spring II6 to apoint below the outer surface of packingring 98 so that said packing ring member 96 is in a, position to engagethe upper surface of the record-disk in the magazine before said surfaceis engaged by gasket 90 while the suction-head is descending forengaging the record-disk. During the descent of the suction-head from aposition above the record-disk to a position in which the pick-up plateengages xsaid disk, the lower edge of packing ring 92 is engaged by therecord-disk and moves upwardly with member 96 in hub part |84 againstthe resilient pressure of spring II6 and packing ring 98 engages theupper surface of said record-disk. The upward movement of member 96 inhub part |84 is limited by a shoulder II8 of hub member |84.

In order to xedly secure packing ring 92 to member 96 in such manner asto prevent movement thereof. longitudinally of said member, the

outer surface portion I28 of member 96 is tapered upwardly. It will beobserved that as shown in Fig. 4, the packing member 92 extendsdownwardly below the lower end of member 96 to provide said packingmember withel lower resilient end portion whichis not interfered with bythe assaieo f carrying member 96. The flange |22 prevents movement ofgasket 92 upwardly on member 96. The outer surface of gasket 92 ispreferably cylindrlcal in parallel relation to the adjacent innercylindrical surface of hub member |04.

It will be understood that after the recorddisk is moved from Athesupply magazine and placed on the turn-table T, the suction-head remainsin engagement with the upper surface of the record and rotates therewithduring the rotation of the record by the turn-table, the weight suctionhead is raised to lift the record from the turn-table and then thecarrier is turned to position the record over the discharge chute C.

chute to the discharge opening of the cabinet shown in my priorapplication.
